AI Technical Summary

Technical Problem

Existing shock absorption mechanisms for tractor coupling seats are mostly unidirectional, which causes collisions between the tractor and trailer when starting or braking, shortening their service life and resulting in low buffering efficiency.

Method used

It adopts a bidirectional buffer mechanism combined with a multi-level buffer structure, including a reverse buffer mechanism and a buffer assembly. It achieves bidirectional and multi-level buffering through mechanical structures such as return springs, telescopic rods, and buffer columns. The structural design is optimized to improve durability and light weight.

Benefits of technology

It achieves bidirectional buffering under complex working conditions, improves buffering efficiency, extends the service life of connecting parts, reduces vibration and impact, and enhances driving stability and cargo protection.
